Known Issues In Red Hat Enterprise Virtualization 3.1

biosdevname Names SR-IOV Virtual Function From Intel rNRC As ethN

Description Servers installed with RHEV 3.1 and Intel Ethernet NDC controller, the biosdevname 0.3.11

utility names the SR-IOV virtual functions from 10GbE port of Intel rNRC as ethN. The VFs are

named ethN instead of the following format:

em<port number>_<virtual function instance>

This issue affects Dell PowerEdge 12th generation platforms with on-board network adapters

NDC, which support SR-IOV when SR-IOV is enabled for the adapters.

Workaround To turn off the new naming convention, enter the kernel command line parameter,

biosdevname=0 in the boot command line during and after installation. This issue is fixed in

biosdevname-0.4.0. For more information, see http://linux.dell.com/biosdevname/

biosdevname-0.4.1/.

NOTE: This issue is fixed in RHEV 3.2.

Cause SR-IOV virtual functions from on-board network adapters do not have SMBIOS type 41 records.

To retrieve the port number, use the SMBIOS device type instance from the physical function

that has the virtual functions.

Unable To Configure RHEV 3.1 Home Page Setup, After Accessing It Multiple Times

Description RHEV 3.1 home page becomes unresponsive when the setup parameters are accessed multiple

times, displaying the following error:

Maximum recursion depth exceeded.

Cause The Text User Interface becomes unresponsive when you use the arrow keys to move between

different pages repeatedly (over 200 times).

Known Issues In Red Hat Enterprise Virtualization 3.0

Disk Description Unknown While Installing RHEV-H On SUT

Description While installing RHEV-H on SUT, disk displays UNKNOWN in the Description field.

NOTE: This issue occurs only with SAS disks.

NOTE: This issue is fixed in RHEV 3.2.

Cause In earlier versions, ID_SCSI_COMPAT was the value for Description under Disk Details in the

storage selection screen. If ID_SCSI_COMPAT is not defined for a device, the device checks

for virtio disk. If virtio disk does not exist, UNKNOWN is displayed in the Description field.
